TOP-PLATE-LIFTING DEVICE.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed May 14, 1913. Serial No. 767,683.

To all whom "it may concern Be it known that I, GEORGE PIoKUP, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Top-Plate-lllifting Devices, of which the following is a specification.

The object of this invention is to provide an improved means for raising and holding in the desired position the movable top plate of a cook stove or range, for the purpose either of introducing fuel into the fire box, or of toasting or broiling food over the coals therein.

In the accompanying drawings, Figure 1 is a view illustrating in side elevation a device embodying the features of my invention, said view showing the manner in which the device is mounted upon the cook stove. Fig. 2 is a fragmental elevation from the opposite side of the device. Fig. 3 is a top plan view. Fig. 4 is a sectional view taken in the vertical plane of line i of Fig. 1. Fig. 5 is a fragmental rear elevation of a steel range having associated therewith a top plate lifting device constructed in accordance with my invention.

Referring to Fig. 5. A indicates the body portion of a steel range, B the rear end wall of the fire box, C the top of the-range, and l) the movable section or top plate which is mounted for upward swinging movement about an axis adjacent to one edge to expose the interior of the fire box. The pivotal connection between the top plate D and the body of the range may be of any suitable or preferred form, being herein shown as com prising a suitable number of curved projections E on the section D, said projections extending through openings in the top C.

Fixed to one corner of the top plate D near its pivoted edge is a downwardly projecting arm 6, said arm being secured to the top plate in any common or preferred way. A bracket 7 is secured to the under side of the top C near the end of the range, said bracket having a central opening 8 therein and having rack teeth 9 formed in its lower edge. An angular or L-shape lever 10 has its upper end pivoted at 11 to the upper portion of the bracket 7 and to the middle portion or the angle of this lever is pivoted one end of a link 12, the other end of said link having an elongated opening 13 therein into which extends a stud on the lower end of the arm 6. The link 12 is preferably attached to the lever 10 at the side adjacent to the bracket '7, a portion 1% of said bracket being offset to accommodate the link. One end of the link lies in the central opening 8 of the bracket and in the vertical plane thereof. The end of the link thus forms a stop which abuts against the wall of the opening 8 when the lever 10 is swung to raise the top plate D, so as to limit the swinging movement of the lever ll) and thus prevent the top plate D from being swung too far upwardly. A deg 15 is pivotally mounted between its ends on the side of the lever next to the bracket 7 and at a point 16 near the free end of the lever, the tooth 17 of said dog being arranged to engage the rack teeth 9 on the bracket 7. The opposite end 18 of the dog is enlarged to form a weight which tends to maintain the tooth 17 in engagement with the rack 9. A guard finger 19 on the dog 15 projects past the bracket 7 at the side opposite to the lever 10, said finger engaging a curved rib 20 on the bracket 7 and thus holding the lever 10 in proper position to maintain the tooth 17 in line with the rack 9. The finger 19 and tooth 17 lie in diliierent vertical planes, as shown in Fig. 3.

A handle 21 is pivotally connected at 22 to the free end of lever 10, the adjacent portions of the lever and handle overlapping and having shoulders 23 arranged to abut when the handle 21 is raised.

The normal position of the parts, with the top plate D closed, is indicated in dotted lines in Fig. 1. If it is desired to raise the top plate, the handle 21 is grasped and raised to swing the lever 10 upwardly, which will swing the arm 6 through the medium of the link 12. In the upward movement of the lever 10, the dog 15 engages the successsive teeth of the rack 9 and thereby holds the top plate in the desired position. The handle 21 may then be swung down so as to be out of the way. lVhen the top plate is to be lowered, the weighted end 18 of the dog 15 is raised to disengage the tooth 17 from the rack, whereupon the lever 10 and handle 21 will swing downwardly to permit the descent of the top plate D into its normal position. The top plate may be supported at any angle of elevation by engaging the dog 15 with the proper one of the rack teeth 9.

My invention is not limited to the precise shape and arrangement of parts shown in the drawings, but may be embodied in modilied forms without departing from the scope of the invention as defined in the appended claims.

I claim as my invention:

1. In a stove, the combination of a body, a top plate section mounted thereon for pivotal movement, a downwardly projecting arm rigidly carried by said section, a bracket rigidly mounted on said body beneath the top of the stove, said bracket having a rack at its lower edge, a lever pivoted at its upper end on said bracket and normally hanging downwardly from said pivot, a link having one end pivotally attached to said lever at a point between the ends of the lever, the opposite end oil said link being attached to said arm, and a dog pivoted bet veen its ends on said lever, one end of said dog being arranged to engage said rack and the opposite end ot the dog being weighted to normally hold the dog in such engagement.

2. In a stove, the combination of a body, a top plate section mounted thereon for pivotal movement, a downwardly projecting arm rigidly .iixed to said top plate section, a downwardly projecting bracket fixed to said body and having rack teeth in its lower edge, said bracket having a central opening therein, a lever having its upper end pivoted to said bracket at a point above said opening, said lever normally hanging downwardly from its pivot, a link connected at one end to said arm, the opposite end (it said link being attached to said lever at a point between the ends of the lever, the last mentioned end of the link lying in the opening in said bracket and arranged to abut against one wall. of said opening to determine the upward swinging movement of the top plate section, and a dog pivoted on said lever adjacent to the "free end of the latter and adapted to engage the rack teeth in said bracket for holding said top plate section in its elevated position.

3. In a stove, the combination. of a body, a. top plate section mounted for pivotal movement thereon, a bracket mounted on said body and carrying a rack, a lever pivoted on one side of said bracket, means including a link for connecting said lever to said top plate section, a dog pivoted between its ends on said lever, said dog comprising a tooth adapted to engage said rack, a weighted portion at the opposite side ofthe pivot point, and a guard finger engaging said bracket at the side opposite to said lever.

t. In a stove, the combination of a body, a top plate section mounted thereon for pivotal movement about an axis adjacent to one edge, a. downwardly extending arm fixed to said section near said edge, a bracket mounted on said body and carrying a rack, a lever pivoted at its upper end on said bracket, a link having one end pivotally attached to said lever at a point between the ends of the latter, said link being attached at its other end to said arm, and a dog pivotally mounted on said lever adjacent to its free end, said dog being arranged to engage said rack for holding said top plate section in its elevated position.

5. In a stove, the combination of a top comprising a section pivoted at one edge, a downwardly extending arm fixed to said section near said edge, a bracket secured to the underside of said top and having a rack at its lower edge, a lever pivoted at its upper end on one side of said bracket, a link having one end pivoted to said lever between the ends of the latter, the other end of said link being attached to said arm, a dog pivotally mounted on said lever near the free end thereof, said dog comprising a tooth at one side of the pivot point arranged to en.- gage said rack, a weighted portion at the opposite side of the pivot point arranged to hold the tooth in such engagement, and a guard finger lyin at the side of said bracket opposite to said lever for holding the parts in proper position.

in testimony whereof I allix my signature in the presence of two witnesses.
